[0013] Technical effects and advantages of the present invention: 1. The present invention arranges the square filter screen and the square opening inside the drying plate in an interlaced state, and the drying plate is located on the side of the square opening. The interior of the switch cabinet is detected by a temperature sensor. When the internal temperature of the switch cabinet is high, the drying plate moves to the right inside the guide frame and the sliding track. According to the internal temperature data of the switch cabinet, the diameter of the interlaced connecting part of the square opening and the ventilation slot is controlled, thereby controlling the dissipation speed of the air inside the switch cabinet, so that the heat dissipation speed of the switch cabinet can be adjusted, thereby enabling the switch cabinet to adapt to different regions and environments, and improving the self-adaptability of the switch cabinet.

[0014] 2. The present invention sets a pressing block to press the pressing switch, and rotates the fan assembly toward the inside of the switch cabinet. At this time, the square opening becomes an air inlet and is discharged through the second vent. At the same time, the wind speed of the fan assembly is controlled according to the degree to which the pressing block presses the pressing switch, thereby secondary adjusting the circulation rate of the air inside the switch cabinet, thereby converting the switch cabinet from passive heat dissipation to active heat dissipation, making the heat dissipation effect more ideal. At the same time, the fan assembly is automatically turned on and off to make the switch cabinet more energy-saving and environmentally friendly.

[0015] 3. The present invention dries the internal air entering the switch cabinet by setting a drying plate, so as to prevent humid air from entering the switch cabinet and affecting the normal operation of the internal electrical appliances. When the humidity sensor detects that the humidity of the switch cabinet is high, the front of the fan assembly is directed toward the drying plate. At this time, the square opening is converted into an air outlet state, so that the drying plate is dried. Subsequently, the drying plate absorbs the humid air inside the switch cabinet again, so that the inside of the switch cabinet is always in a dry state, avoiding the influence of humidity on the internal components of the switch cabinet, improving the safety of the switch cabinet, and extending the service life of the internal components.

[0016] 4. The present invention provides a second vent so that the wiping cotton is wrapped around the outer surface of the guardrail. By pushing the pushing block, the moving rod is moved inside the filter screen cover. The bristles and the wiping cotton clean the surfaces of the filter screen cover and the guardrail respectively, so that the filter screen cover and the guardrail can be cleaned without disassembly. At the same time, the placement limit plates at both ends of the filter screen cover can be separately pulled out from the placement rack for cleaning, so that the switch cabinet is easy to clean and flexible to use.

[0017] The present invention provides a cleaning brush. When the switch cabinet body itself controls the drying plate to move and the square filter screen moves, the cleaning brush will slide on the surface of the square filter screen, so that the attached dust is swept off by the cleaning brush. Due to the action of gravity, part of the dust is discharged through the square opening, and part of the dust falls into the interior of the sliding track and is discharged through the dust discharge port, thereby achieving self-cleaning and avoiding the influence of dust on the air inlet, thereby improving the heat dissipation effect of the switch cabinet itself.

At the same time, the placement limit plates 65 at both ends of the filter screen cover 63 can be separately pulled out from the placement rack 62 for cleaning.

[0038] Working principle of the present invention: when in use, the drying plate 011 in the initial state is located on the left side of the first ventilation opening 3. At this time, the square filter 016 inside the drying plate 011 and the square opening 15 are in a staggered state, and the drying plate 011 is located on the side of the square opening 15. The inside of the switch cabinet 1 is detected by the temperature sensor 7. When the internal temperature of the switch cabinet 1 is high, the temperature sensor 7 converts it into an electrical signal and transmits it to the rotation drive 22, and controls the rotation drive 22 to drive the rotating screw 23 to rotate. At this time, the drying plate 011 moves to the right inside the guide frame 21 and the sliding track 11. According to the internal temperature data of the switch cabinet 1, the diameter of the staggered communication part of the square opening 15 and the ventilation slot 014 is controlled, thereby controlling the dissipation speed of the air inside the switch cabinet 1; When the diameters of the ventilation slot 014 and the square opening 15 are at their maximum and the temperature inside the switch cabinet 1 is still high, the rotary drive 22 continues to control the drying plate 011 to move to the right. At this time, the pressing block 013 presses the pressing switch 9, so that the multi-stage electric telescopic rod 54 controls the fixed rack 55 to extend and descend, and pushes the rotating gear 56 to rotate. The rotating rod 52 drives the fan assembly 53 to rotate, and causes the fan assembly 53 to rotate toward the inside of the switch cabinet 1. At this time, the square opening 15 becomes an air inlet and is discharged through the second vent 6. At the same time, according to the degree to which the pressing block 013 presses the pressing switch 9, the wind speed of the fan assembly 53 is controlled, thereby adjusting the circulation rate of the air inside the switch cabinet 1 for a second time, so that the heat dissipation speed can be adjusted; In addition, by providing a cleaning brush 14, when the switch cabinet 1 itself moves by controlling the drying plate 011, the square filter 016 moves, and the cleaning brush 14 slides on the surface of the square filter 016, so that the attached dust is swept off by the cleaning brush 14, and part of the dust is discharged through the square opening 15 by gravity, and part of the dust falls into the interior of the sliding track 11 and is discharged through the dust discharge port 13; By setting the drying plate 011, the internal air entering the switch cabinet 1 is dried to prevent humid air from entering the switch cabinet 1 and affecting the normal operation of the internal electrical appliances. When the humidity sensor 8 detects that the humidity of the switch cabinet 1 is high, the humidity of the drying plate 011 itself is high and the water absorption is relatively saturated. The humidity sensor 8 controls the multi-stage electric telescopic rod 54 to contract through electrical signal transmission, and the rotating gear 56 rises and reverses, so that the front of the fan assembly 53 faces the drying plate 011. At this time, the square opening 15 is converted into an air outlet state. Subsequently, the rotating drive 22 controls the guide frame 21 to drive the drying plate 011 to move slowly, and generates hot air through the temperature of the internal components of the switch cabinet 1 to dry the surface of the drying plate 011, so that the drying plate 011 is dried. Subsequently, the drying plate 011 absorbs the humid air inside the switch cabinet 1 again to dry the inside of the switch cabinet 1. At the same time, by setting the second vent 6, the wiping cotton 68 is wrapped around the outer surface of the guardrail 61, and by pushing the pushing block 69, the moving rod 66 is moved inside the filter screen cover 63, and the bristles 67 and the wiping cotton 68 clean the surfaces of the filter screen cover 63 and the guardrail 61 respectively. The fallen dust is inside the filter screen cover 63. When the second vent 6 is an air outlet, the dust is discharged to the outside of the switch cabinet 1 along with the air, so that the filter screen cover 63 and the guardrail 61 can be cleaned without disassembly. At the same time, the placement limit plates 65 at both ends of the filter screen cover 63 can be pulled out from the placement rack 62 separately, and then cleaned separately.
